Provided is nonwoven fabric which has first protrusions that protrude toward the first-surface side on which the nonwoven fabric sheet is viewed from a plan-view direction and recesses that are recessed toward the second-surface side which is opposite to the first-surface side, and in which the first protrusions and the recesses have been alternately and successively arranged, with wall parts interposed therebetween, in different directions that cross in the plan view of the nonwoven fabric, each wall part having fiber orientation in the direction that connects the top of the first protrusion and the bottom of the recess. In the nonwoven fabric, (Ta/T)×100 (%) is 50% or more, where Ta is the thickness of the first protrusions including the apexes thereof and T is the thickness of the entire nonwoven fabric viewed from a side-view direction. The nonwoven fabric comprises fibers differing in fineness. |
